Title: Improvements in and relating to the production of catalysts
IPC: C07C5/27
Filed: 1949-12-02
Abstract: Hydrocarbon conversion reactions, e.g. the conversion of tertiary butyl benzene to benzene and isobutene at 400 DEG  C. and p-xylene to a mixture of o- and m-xylenes at 430 DEG  C., are carried out with a catalyst comprising one or more oxides of Al, Zr, Be, Th and Ti which have been treated with gaseous hydrogen fluoride (see Group III).ALSO:A catalyst for hydrocarbon conversion reactions (see Group IV (b) is prepared by contacting a substance containing one or more oxides of Al, Zr, Be, Th and Ti with gaseous hydrogen fluoride without the application of external heat and until the substance undergoes a distinct increase in weight.  The catalyst may also include silica or magnesia and the oxide to be treated may be a silica-alumina gel.  Inert gases, e.g., nitrogen, may be admixed with the hydrogen fluoride.  The metal oxide is preferably substantially free from alkali-metal compounds and methods of obtaining alumina in such a condition are described; similarly a silica-alumina gel may be prepared as described in Specification 649,999.  The catalyst may be regenerated in air at 450 DEG -700 DEG C. and reactivated by a further treatment with gaseous hydrogen fluoride.

Title: Combined pneumatic and spring suspensions, in particular for railway vehicles
Inventor: HIRST ARCHIE JOHN
IPC: F16F9/04
Filed: 1957-10-03
Abstract: 855,814. Railway vehicles undercarriages; rubber and pneumatic springs. METALASTIK Ltd. Sept. 25, 1958 [Oct. 3, 1957], No. 31057/57. Classes 103(6) and 108(3). A railway vehicle bolster 5, Fig. 2, positioned between a pair of transoms 7 on a frame 6, is supported at each end on each side by a hollow composite spring 9 of rubberlike material and metal, extending between a wedge member 8 on a transom and a corresponding member 14 on the bolster, and filled with compressed air. Each spring 9 which is inclined upwardly and inwardly of the bolster comprises rings 10 of rubber-like material bonded to metal ring interleaves 11 and the ends are sealed by plates 12. Mounted between circular recesses in the plates 12 and in the wedges 8, 14, are circular plates 16 bonded to the ends of circular blocks 15 of rubberlike material. The interior wall of the hollow spring 9 is coated with a flexible synthetic rubber to prevent attack on the wall by oil which may be present in the compressed air e.g. supplied from the vehicle brake system. The pressure of the air is controlled by a valve means one element of which is connected to the bolster whilst the other is connected to the frame whereby the body of the vehicle is maintained at a predetermined datum height relative to the frame. The valve means may be adjusted upon variations in the height of the body relative to the ground e.g. relative to a wheel axle, and is arranged to be inoperative when the vehicle is moving. In another embodiment shown in Fig. 3, only one spring 9 is provided at each end of the bolster 5 and on one end the same side thereof and in combination with a tension link 21 secured between a single transom 20 and the bolster 5. Each end of the link 21 carries a part-spherical head 24 co-operating with a part-spherical socket 23 with the interpositioning of rubber interlayers 25 and a metal interleaf 26, which interlayers serve as seals for the hollow spring 9.

Abstract: 729,588. Liquid fuel burners. KONSTANDT, F. G. Dec. 10, 1952, No. 31226/52. Class 75 (1). In a wick burner in which liquid fuel is vaporized and burnt in an annular space between coaxial perforated walls 6, 8, Fig. 2, and wherein wicks feeding the flame are enclosed in tubes movable inside other tubes arranged in a circle, the inner tubes being connected to carrier members vertically displaceable by external control means whilst the outer tubes are fixed and serve to space the combustion chamber 6, 8 from the fuel tank 1, tubes 11 containing the main flame wicks 16 are fixed to one carrier member 13, whilst tubes 10 containing pilot flame wicks 29 are fixed to another carrier member 12, the wicks 29 are arranged between the wicks 16, as illustrated in Fig. 3, and manually operable means are provided for independently moving the carriers 12, 13 upwardly or downwardly. The outer tubes 3, 4 are mounted on the cover 2 of the fuel container 1 and support at their upper ends the base 5 of the vaporizing and combustion chamber formed between the upwardly divergent perforated cones 6, 8 or between perforated cylinders. The number of wicks 16, e.g. eight, is preferably twice the number of wicks 29, e.g. four. The carrier 13 is adjustable vertically by rotating by a control knob 18 a shaft 17 mounted on supports 19, 20 so that a radial arm 21 on said shaft actuates a pivoted link 22 connected to the carrier 13. For raising and lowering the carrier 12 a sleeve 26 on the shaft 17 is rotatable by a handle 25 so that a radial arm 27 on the sleeve 26 actuates a pivoted link 28 connected to the carrier 12. To reduce heating of the fuel container 1 by thermal conduction through the tubes 3, 4, these are at least 1¢ inches long and are each formed by rolling very thin iron sheet to form a tube having a double wall a, c, Fig. 9. The inner wall a projects beyond the outer wall c so that the tube may be fixed between the cover 2 and the base 5 of the combustion chamber by turning over the ends of the wall a. Each wick 16 or 29 comprises an asbestos burning wick portion 38, Fig. 10, supplied with oil through a cotton wick 37, the junction between the portions 37, 38 being surrounded by a wire mesh 39. The projecting end 41 of an internal wire 40 forms a stop for locating the wick at the required level in the tube 10 or 11. The wire mesh 39 may be replaced by a long sleeve perforated at the upper end.
